Profile

She was the physical incarnation of the goddess Astarte. Lilith of Darkness encouraged her to believe that she was the true goddess of the Moon, not Sailor Moon, and as such should be the ruler of the world. This effort was motivated by Lilith's intent to bring her to Death Vulcan's side during the battle against the Sailor Senshi, and also to use Astarte's powers and her body as a vessel for Dark Cain. Baron Gilles de Rais showed concern about Astarte's ultimate role in the battle, as Dark Cain had said that once the goddess was fully awakened, it was impossible to know which side she would choose. Lilith, however, thought it was unimportant, as either way the fate of humanity would be determined soon.
